摘要
从影响顶板稳定性的基本因素、评价指标出发， 根据大姚顶板岩体的参数和实际盘区顶板稳定性的分析， 优选和论证了大姚盘区的结构参数。其分析方法对顶板稳定性评价， 有一定参考价值。
Fundamental factors influencing roof stability and their evaluation indices are dealt with in this paper.Structure parameters of the Dayao panel are optimized and documented based on analyses of roof rock parameters and real roof stability of this panel. This analytical method could be a worthwhile reference for roof stability evaluation.
